Chapter 24 uses the metaphor that people are 'blind despite having eyes.' What is the meaning behind this statement?

The statement in Chapter 24 that people are 'blind despite having eyes' refers to a state of spiritual ignorance rather than a physical condition. The chapter clarifies that this blindness is caused by the 'strength of their body-consciousness,' which prevents them from understanding their own true welfare. This preoccupation with the self and momentary physical pleasures makes them forget the transient nature of the body. As Chapter 24 suggests, this spiritual blindness keeps them from perceiving the path to their ultimate good.
